The preparation of a stable trivinyl carboniumion is described. A detailed evaluation and comparison of the n.m.r. spectrum of this ion with other stable carboniumions, coupled with the use of ultraviolet spectroscopy, is used for the structure proof. The synthesis of the necessary tetraene precurser and the cyclization reactions of the above ion are also described. Comparisons of the cyclization
